Compat Test Skill

Compat Test Skill

A minimal third-party skill used by the harness compatibility gate. It reads a text file, emits a short summary, and declares the summary file as a deliverable artifact via the documented files_to_send field.

This skill intentionally avoids any runtime-internal types. It uses only the stable developer interface fields documented in docs/app-skill-dev-guide.md:

• manifest.json: name, version, author, description, timeout_secs, requires_network, tools[].name, tools[].description, tools[].input_schema, tools[].env
• SKILL.md frontmatter: name, description, version, author, always, requires_env
• Binary protocol: ./main <tool_name> with JSON on stdin, JSON with output, success, files_to_send on stdout.

Tools

summarize_text

Reads a text file at input_path, writes a compact summary to output_path, and returns output_path as a deliverable artifact.

Parameters:

• input_path (required): absolute path of the source text file
• output_path (required): absolute path to write the summary to

Secret Handling

The skill declares COMPAT_SUMMARY_TOKEN via requires_env and tools[].env. The runtime strips secret-like environment variables from plugin subprocesses unless allowlisted in tools[].env. The skill NEVER writes the secret value to stdout, stderr, or disk — only the declared env-var name appears in the manifest and SKILL.md.
